Abstract

The invention relates to a process and an installation for casting a metal strip (9), in particularly a steel strip, according to which, the solidification of the strip (9) is achieved by passing the molten metal between two strip rolls which rotate in opposite directions (1,1') in relation to the horizontal axes and are cooled by the circulation of a cooling fluid and define a casting space between said rolls having a rough outer surface the casting space being rendered inert by blowing gas or gas mixture through a cover (10) covering the casting space, characterized in that the camber of the rolls (1,1') is controlled by modulating the quantity of blown gas and /or the nature of the gas or the composition of the gas mixture, at least around the surface of each roll (1,1') upstream of the contact zone with the molten metal (2). According to the invention, the installation comprises some means (25,25',26) for measuring and calculating the camber of the strip roll (1,1') in the casting space which is covered by a cover (10) wherein the gas or the mixture of gases is blown through the orifices of two blocks (11,11') having a bottom face (12,12') defining a space with a surface (3,3') of the rolls (1,1'). The measuring means (25,25',26) comprise at least a set of contactless sensors (25,25').
